Supported Au nanoparticles (NPs) have attracted much attention in catalytic field because of their high activity and selectivity. However, its activity was affected by its dispersion. In this work, a controlled impregnation method was used to prepare Au/Zn-hydrotalcites (Au/Zn-HTs). The role of lattice Zn2+ in controlling Au NPs was studied. The size, structure, and composition of Au NPs were characterized...
